三、交流電機(jī)的優(yōu)點(diǎn)
1.交流電機(jī) 制造比較便宜。
2.矢量變頻技術(shù)的發(fā)展，已經(jīng)可以用變頻電機(jī)模擬成直流電
3.相對(duì)于直流電機(jī)在結(jié)構(gòu)簡(jiǎn)單、維護(hù)容易、對(duì)環(huán)境要求低以及節(jié)能和提高生產(chǎn)力等方面具有足夠的優(yōu)勢(shì)，使得交流調(diào)速已經(jīng)廣泛運(yùn)用于工農(nóng)業(yè)生產(chǎn)、交通運(yùn)輸、國(guó)防以及日常生活之中。
四、交流電機(jī)的缺點(diǎn)
1.交流電機(jī)的啟動(dòng)性和調(diào)速性較差
交流電機(jī)根據(jù)轉(zhuǎn)速可分為同步電機(jī)和異步電機(jī)。

在生產(chǎn)機(jī)械中廣泛使用不改變同步轉(zhuǎn)速的調(diào)速方法有繞線式電動(dòng)機(jī)的轉(zhuǎn)子串電阻調(diào)速、斬波調(diào)速、串級(jí)調(diào)速以及應(yīng)用電磁轉(zhuǎn)差離合器、液力偶合器、油膜離合器等調(diào)速。改變同步轉(zhuǎn)速的有改變定子極對(duì)數(shù)的多速電動(dòng)機(jī)，改變定子電壓、頻率的變頻調(diào)速有能無(wú)換向電動(dòng)機(jī)調(diào)速等。
從調(diào)速時(shí)的能耗觀點(diǎn)來(lái)看，有調(diào)速方法與低效調(diào)速方法兩種：調(diào)速指時(shí)轉(zhuǎn)差率不變，因此無(wú)轉(zhuǎn)差損耗，如多速電動(dòng)機(jī)、變頻調(diào)速以及能將轉(zhuǎn)差損耗回收的調(diào)速方法（如串級(jí)調(diào)速等）。有轉(zhuǎn)差損耗的調(diào)速方法屬低效調(diào)速，如轉(zhuǎn)子串電阻調(diào)速方法，能量就損耗在轉(zhuǎn)子回路中；電磁離合器的調(diào)速方法，能量損耗在離合器線圈中；液力偶合器調(diào)速，能量損耗在液力偶合器的油中。一般來(lái)說(shuō)轉(zhuǎn)差損耗隨調(diào)速范圍擴(kuò)大而增加，假如調(diào)速范圍不大，能量損耗是很小的。

一般場(chǎng)所應(yīng)選用II類手持式電動(dòng)工具并應(yīng)裝設(shè)額定觸電動(dòng)作電流不大于15mA，額定動(dòng)作時(shí)間小于.1s的漏電保護(hù)器。若采用I類手持式電動(dòng)工具，還必須作接零保護(hù)。操作人員必須戴絕緣手套、穿絕緣鞋或站在絕緣墊上。在潮濕場(chǎng)所或金屬構(gòu)架上操作時(shí)，必須選用II類手持式電動(dòng)工具，并裝設(shè)防濺的漏電保護(hù)器。嚴(yán)禁使用I類手持電動(dòng)工具。狹窄場(chǎng)所（鍋爐、金屬容器、地溝、管道內(nèi)等）宜選用帶隔離變壓器的III類手持式電動(dòng)工具；若選用II類手持式電動(dòng)工具，必須裝設(shè)防濺的漏電保護(hù)器。
